Easy on. Easy off. Easy on the planet. These adidas Stan Smith Shoes are crafted from recycled materials, part of adidas' commitment to end plastic waste. With a synthetic leather upper and an outsole made from rubber waste, they redefine an iconic style. Hook-and-loop straps make them easy to get into when you're heading out the door and even easier to kick off at the end of the day. This product is made with Primegreen, a series of high-performance recycled materials. 50% of upper is recycled content. No virgin polyester.
